Rechargeable zinc-air batteries (<em>Re</em>-ZABs) emerged as a viable alternative for consumer electronics and electric vehicles, offering extended operational life and improved safety features. Recent advancements in <em>Re</em>-ZAB technology have been focusing on enhancing key components, such as air cathodes, zinc (Zn) anodes, and gas diffusion membranes, to improve energy storage capacity and battery lifespan. However, widespread commercial adoption remains hindered by persistent challenges, including dendrite formation, Zn anode passivation, corrosion, and limited charge-discharge cycles. Additionally, the slow kinetics of oxygen electrochemical reactions (oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER)), and the interaction of oxygen with battery components present significant technical barriers. The development of durable and efficient oxygen electrocatalysts is essential for advancing <em>Re</em>-ZABs and related energy conversion technologies, such as fuel cells and water-splitting systems. This review provides a comprehensive overview of ZAB fundamentals, covering the transition from primary ZABs (Pr-ZABs) to rechargeable systems, alongside strategies to enhance battery efficiency and rechargeability. Particular attention is given to addressing Zn anode challenges, improving air cathodes, and evaluating the latest progress in unifunctional, bifunctional, and trifunctional electrocatalysts, including noble metal, transition metal, metal-organic framework (MOF)-based, and carbon-based materials. Finally, future research directions and potential advancements in <em>Re</em>-ZAB technology are explored, emphasizing their role in sustainable energy solutions.</div></div>","PeriodicalId":93548,"journal":{"name":"Energy nexus","volume":"17 ","pages":"Article 100387"},"PeriodicalIF":8.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study analyzes the compatibility of alternative inorganic, nontoxic, cesium-based planar (n-i-p) perovskite solar cells (PSCs), specifically Cs₃Bi₂I₉ and CsSnI₃, with various charge transport layers (CTLs) to enhance power conversion efficiency (PCE). A total of eight PSC configurations were simulated using SCAPS-1D software, with the selected CTLs including GO, MoS₂, CeO₂ and WO₃. The initial optimization step involved adjusting the absorber thickness, leading to enhanced photon absorption and increased PCE across all configurations. Further optimization of CTL doping, carrier mobility, and electron affinity improved band alignment, electric potential distribution, and cell conductivity. These optimizations reduced recombination losses and enhanced charge carrier extraction. A second round of absorber thickness optimization was then performed, accounting for the changes induced by the previous steps. As a result, the PCE improved significantly, with the highest efficiency reaching 21.52% in the GO/CsSnI₃/CeO₂ structure. Other optimized configurations, such as GO/CsSnI₃/WO₃ and MoS₂/CsSnI₃/WO₃, achieved PCE values of 21.4% and 15.64%, respectively.

This study concentrates on the proposition and techno-economical investigation of a hybrid wind-solar energy system encompassing flat plate solar collector for the purpose of clean hydrogen and electricity generation. The proposed system is a combination of flat plate solar collectors, wind turbine, organic Rankine cycle, and proton exchange membrane electrolyser. Wind speed, turbine inlet temperature, incident solar irradiation, and collector-related parameters including its surface area and fluid mass flow rate are selected decision variables, the impacts of which on the exergy efficiency and exergy loss of the scheme are examined. The objective functions included total cost rate and total exergy efficiency. The Nelder-Mead optimization method and EES software were utilized to achieve the mentioned goals, followed by a comparative case study was conducted for two cities with high potential in Iran. According to the optimization results, the exergy efficiency of 13.35 % was achieved while the cost rate was equal to $25.48 per hour, respectively. According to the sensitivity analysis, the increment in the solar collector area, incident solar irradiation, wind speed, and turbine inlet temperature improved the system's technical performance. Furthermore, the exergy loss analysis pointed out that the increment in the turbine inlet temperature, not only improves the system's performance, but also reduces the exergy loss.

Based on panel data from 257 Chinese cities between 2013 and 2019, this paper investigates the relationship between the development of urban digital trade and carbon emissions in depth. The analysis reveals an inverted U-shaped relationship between digital trade and carbon emissions: during the early stages of digital trade development, carbon emissions increase, but after reaching a certain threshold, carbon emissions gradually decline. This conclusion remains robust following endogeneity tests. Further examination indicates that the market integration plays a dynamic moderating role in this relationship: a higher market integration flattens the inverted U-shaped curve and shifts the inflection point to the left, meaning that the positive impact of digital trade on carbon emission reduction occurs at an earlier stage. Additionally, the study highlights that varying levels of industrial structure, green innovation, and digital infrastructure exert heterogeneous effects on the inverted U-shaped relationship. Specifically, cities with higher levels of industrial structure, green innovation, and digital infrastructure tend to enter the carbon emission reduction phase earlier.

It also predicts the future responses of the studied ecosystems to SE and RF for the upcoming 20 years. The study was conducted in the eastern Mediterranean from 2019 to 2038, 2019 served as the reference year to compare WEPP model output with measured values at the studied locations.

Future projections revealed that the agricultural ecosystem exceeded others in terms of SE and RF.
